I am very impressed with the quailty of this set of Bluetooth headphones.sound sounds amazing coming from the speakers.bass sounds extremely good.very easy to use and the part I really like the most is how long the battery last.many hours!!if one was to buy this product for themselves they would not be let down at all.this brand I trust and recommend,and the seller of it.comes in a nice box and included is instructions headset and charger plug. This is a light weight set that shouldnt put strain on your neck. I love these headphones.#rankbooster#ecandy#awesomeproduct#iloverankbooster
